Product Description

SIGMA prefabricated vertical drains (PVD) comprise a synthetic drainage core wrapped with a durable fabric of excellent filtration properties for accelerated consolidation of soft soil. Accelerated consolidation removes excess pore pressures quickly from soft foundation soil increasing the foundation shear strength to support embankment and fill loadings.

Advantage:

The ground improvement system with SIGMA PVD is very efficient and cost-effective
SIGMA PVD conforms to internationally well-recognized PVD specifications
Consolidation times for soft clay foundation deposits can be significantly reduced from many years to 0.5 to 2 years
The undrained shear strength of the soft clay foundation deposits can be increased when using SIGMA PVD
